Hi,

I'm currently using SDC 3.21 and I'm hitting the error that is also mentioned in this thred - https://issues.streamsets.com/plugins/servlet/mobile#issue/SDC-12129

Any suggestions on how to resolve this issue permanently. At present the only workaround that I've is to restart StreamSets. I did that in development (local) environment. But that's not an option in Production.

Regards

Swayam

@swayam The Jira states that this issue happens when there are some data rules created and the workaround would be to delete those.

Hi @Sanjeev 

“there are some data rules created” - I’m unable to understand what data rules it is reffering to? My pipeline is as below:

 

 

 

 

@swayam here’s the link to the docs that explains data rules - https://docs.streamsets.com/portal/#datacollector/latest/help/datacollector/UserGuide/Alerts/RulesAlerts_title.html#concept_tpm_rsk_zq

If you don’t have the data rules defined, perhaps the issue is caused by something else.

Thanks - actually there is no “Data Rules’ that is configured in pipeline. So the actual cause of the issue is still unknown and there is no elegant recovery from this.

@swayam Please raise a support ticket for the RCA & resolution.
